It is well known that acetyl-l-carnitine (ALC) has various neuroprotective effects against neurodegenerative diseases. In addition, it has been reported that ALC facilitates myelination of regenerated axons after peripheral nerve injuries. We previously reported that spontaneous regeneration of the lateral olfactory tract (LOT), the main fiber tract of the central olfactory system, consistently occurred in newborn rats and a majority of these regenerated fibers were unmyelinated in neonatally LOT-transected young adult rats...

Parkinson's disease (PD) is characterized by the degeneration of dopaminergic neurons in the nigrostriatal pathway that leading to progressive motor and nonmotor symptoms. The formation of newborn neurons in the adult hippocampus is affected by many factors such as anxiety, depression and impairment in learning and memory that are commonly observed nonmotor symptoms in PD, indicating the role of adult neurogenesis in PD pathophysiology. Acetyl-l-carnitine (ALCAR), regulate mitochondrial metabolism and has been reported to improve cognitive functions in different neurodegenerative disorders through an unknown mechanism...

Functional hypothalamic amenorrhea (FHA) is a relatively frequent disease due to the combination of metabolic, physical, or psychological stressors. It is characterized by the low endogenous GnRH-induced gonadotropin secretion, thus triggering the ovarian blockade and a hypoestrogenic condition. Up to now various therapeutical strategies have been proposed, both using hormonal treatment as well as neuroactive compounds. Since carnitine, namely l-acetyl-carnitine (LAC), has been demonstrated to be effective in the modulation of the central hypothalamic control of GnRH secretion, we aimed to evaluate whether a combined integrative treatment for 12 weeks of LAC (250 mg/die) and l-carnitine (500 mg/die) was effective in improving the endocrine and metabolic pathways in a group of patients (n = 27) with FHA...

Cyclosporine A (CsA) is an immunosuppressive drug commonly used in organ transplant patients to prevent allograft rejections. Ketamine is a pediatric anesthetic that noncompetitively inhibits the calcium-permeable N-methyl-d-aspartic acid receptors. Adverse drug-drug interaction effects between ketamine and CsA have been reported in mammals and humans. However, the mechanism of such drug-drug interaction is unclear. We have previously reported adverse effects of combination drugs, such as verapamil/ketamine and shown the mechanism through intervention by other drugs in zebrafish embryos...

BACKGROUND: Peripheral nerve injuries repair is still among the most challenging and concern-raising tasks in neurosurgery. The effect of an acetyl-L-carnitin-loaded silicone tube as an in-situ delivery system in defects bridging was studied using a rat sciatic nerve regeneration model. METHODS: A 10-mm sciatic nerve defect was bridged using a silicone tube (SIL/ALC) filled with 10 µL acetyl-L-carnitine (100 ng/mL). In the control group (SIL), the tube was filled with the same volume of the phosphate-buffered solution...

OBJECTIVE: Dietary n-3 polyunsaturated fatty acids (PUFAs), especially eicosapentaenoic acids (EPA) and docosahexaenoic acid (DHA), are proved to be effective in obesity reduction. Microalgal oil (MO) is an important alternative source of n-3 PUFAs that effectively alleviates obesity. The aim of the present study was to explore the anti-obesity effects of microalgal oil from Schizochytrium sp. (SMO) and to compare the effects of 2 SMOs (SMO1 and SMO2) with different levels of purity of n-3 PUFAs on high fat diet (HFD)-induced obesity in male C57BL/6J mice...

A long history of diabetes mellitus and increasing age are associated with the onset of diabetic neuropathy, a painful and highly disabling complication with a prevalence peaking at 50% among elderly diabetic patients. Acetyl-L-carnitine (ALC) is a molecule derived from the acetylation of carnitine in the mitochondria that has an essential role in energy production. It has recently been proposed as a therapy to improve the symptoms of diabetic neuropathy. ALC is widely distributed in mammalian tissues, including the brain, blood-brain barrier, brain neurons, and astrocytes...

L-Carnitine functions to transport long chain fatty acyl-CoAs into the mitochondria for degradation by β-oxidation. Treatment with L-carnitine can ameliorate metabolic imbalances in many inborn errors of metabolism. In recent years there has been considerable interest in the therapeutic potential of L-carnitine and its acetylated derivative acetyl-L-carnitine (ALCAR) for neuroprotection in a number of disorders including hypoxia-ischemia, traumatic brain injury, Alzheimer's disease and in conditions leading to central or peripheral nervous system injury...

Neurodegeneration with brain iron accumulation (NBIA) is a group of neurodegenerative disorders characterized by iron accumulation in the basal ganglia. Recently, mutations in CoA synthase (COASY) have been identified as a cause of a novel NBIA subtype (COASY Protein-Associated Neurodegeneration, CoPAN) in two patients with dystonic paraparesis, parkinsonian features, cognitive impairment, behavior abnormalities, and axonal neuropathy. COASY encodes an enzyme required for Coenzyme A (CoA) biosynthesis. Using whole exome sequencing (WES) we identified compound heterozygous COASY mutations in two siblings with intellectual disability, ataxic gait, progressive spasticity, and obsessive-compulsive behavior...

STUDY QUESTION: How does a maternal diabetic hyperadiponectineamia affect signal transduction and lipid metabolism in rabbit preimplantation blastocysts? SUMMARY ANSWER: In a diabetic pregnancy increased levels of adiponectin led to a switch in embryonic metabolism towards a fatty acid-dependent energy metabolism, mainly affecting genes that are responsible for fatty acid uptake and turnover. WHAT IS KNOWN ALREADY: Although studies in cell culture experiments have shown that adiponectin is able to regulate lipid metabolism via 5'-AMP-activated protein kinase (AMPK) and peroxisome proliferator-activated receptor α (PPARα), data on the effects of adiponectin on embryonic lipid metabolism are not available...

Nonalcoholic steatohepatitis (NASH) is the most frequent cause of liver dysfunction and a common global problem. Gypenosides can decrease pathological modifications of high-fat diet-induced rat atherosclerosis; however, its effect and mechanism on NASH remain unclear. In this study, rats were randomly divided into normal control and model groups. Model rats were fed with a high-fat diet and treated with gypenosides, rosiglitazone, or water for 6 weeks. We found that liver tissues showed significant hepatic steatosis and vacuolar degeneration with significantly higher triglyceride (TG), free fatty acid (FFA) and malonyl CoA, serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) activities in model group versus normal control group (p<0...

BACKGROUND: Neuronal death may be an overlooked and unaddressed component of disability following neonatal nerve injuries, such as obstetric brachial plexus injury. N-acetylcysteine and acetyl-L-carnitine improve survival of neurons after adult nerve injury, but it is unknown whether they improve survival after neonatal injury, when neurons are most susceptible to retrograde neuronal death. The authors' objective was to examine whether N-acetylcysteine or acetyl-L-carnitine treatment improves survival of neonatal motor or sensory neurons in a rat model of neonatal nerve injury...

Tetrahydropalmatine (THP), one of the active components of Rhizoma corydalis, has been reported to exert several pharmacological effects, including anti‑inflammatory, anti‑tumor and analgesic activities. However, its effect on obesity and the underlying molecular mechanisms that may be involved have not yet been elucidated. In the present study, the inhibitory effects of THP on the adipogenesis in 3T3‑L1 adipocytes was examined using hstology, western blotting and RT‑qPCR. THP was identified to significantly suppress lipid accumulation in 3T3‑L1 cells and it inhibited pre‑adipocyte differentiation in a concentration‑dependent manner, as evidenced by the reduced formation of lipid droplets and decreased triglyceride levels and glycerol‑3‑phosphate dehydrogenase activity...

The aim of the present study was to investigate whether cyclosporine A (CSA) improved cardiac dysfunction at an early stage of sepsis. Male Wistar rats were randomly divided into the following three groups: the sham‑operated control group, the cecal ligation puncture (CLP) procedure‑induced sepsis group and the CSA intervention group. Cecal ligation was performed to generate a sepsis model. At different time points (2, 6, 12, 24 and 72 h) following sepsis induction, blood pressure, cardiac function, and non‑esterified free fatty acid (NEFA) levels in the plasma and myocardia were measured, and the expression levels of components associated with the AMP‑activated protein kinase (AMPK)‑acetyl CoA carboxylase (ACC)‑carnitine palmitoyl transferase 1 (CPT1) signaling pathway were compared among the three groups...

A previous study infusing butyrate into the abomasum of sheep produced increased oxygen, glucose, glutamate, and glutamine uptake by the portal-drained viscera. These changes were thought to be partially due to increases in glycolysis and cell proliferation. The purpose of this study was to evaluate the duodenum transcriptome of control and butyrate-treated lambs to determine whether genes involved in these pathways were altered. Polled Dorset lambs ( = 9) received a pulse dose of either butyrate (10 mg/kg BW) or an equal volume of a buffered saline solution (1 mL/kg BW) daily at the time of feeding...
